The Titanic has a mass of 4.2 x 10^7 kg. The Titanic hit an iceberg estimated to be half of her mass. Before hitting the iceberg, the Titanic was estimated to be going 22 knots (11.3 m/s). After hitting the iceberg, the Titanic was estimated to be going about 6.0 knots (3.1 m/s). How fast was the iceberg going after the collision?

Answer: For easy calculations let us consider the mass of Titanic to be m then the mass of Iceberg should be m/2.

No external forces involved so we can safely applied the Momentum conservation law

m*11.3 = m*3.1 +(m/2)*v

m can be cancelled on both sides

(11.3 -3.1)*2 = v

v = 16.4m/s
